CAR COUPLENG.

$PECIPICATION forming part of Letters Patent No. 391.732. dated October 23, 1888.

Application filed June 30, 1888.

To all whom it may concern:

Be it known that I, SOLOMON P. BnNTLEY,a citizen of the United States, residing at Springfield, in the county of Brown and State of Min-. nesota, have invented a new and useful Improvement in Gar-Couplers, of which the following is a specification.

The invention relates to improvements in car-couplers; and it consists in the construc tion and novel combination of parts hereinafter described, illustrated in the drawings, and pointed out in the appended claims.

Figure l of the drawings represents a perspective view of the end of acar having a drawhead illustrative of the invention attached. Fig. 2 represents a plan view of the draw-head with the locking-cylinder detached. Fig. 3 represents a perspective view of the cylinder. Fig. 4 represents a sectional view of the drawhead, the parts being in position to uncouple.

Referring to the drawings by letter, A designates the end of a car, having the recessed draw-head B attached. The said draw-head is of general cylindrical shape, and its mouth or opening I) is oval and extends Vertically, as shown in Fig. 1. The recess b within said draw-head is cylindrical and forms a seat for the coupling-cylinder, hereinafter described.

0 is a transverse rectangular opening in the top of the draw-head and communicating with the recess 2), and D is a similar but narrower opening in the bottom of said draw-head.

E is a cylinder having a twisted bore, 6, which cylinder is seated and partially turns in the recess of the draw-head. The said bore is oval in cross-section and registers normally with the opening 12, having its diameter equal to that of said opening.

F is a curved arm projecting from said cylinder through the opening D, and provided with an adjustable weight, f, that causes the opening I) and the adjacent orifice of the bore 6 to register.

G is a coupling-link bar, having the barbed or lance-shaped heads the points of which stand vertically. WVhen one of said heads enters the draw-head and coupling-cylinder, it rotates the latter partially till it passes therethrough. The cylinder then falls to its nor- Serial No. 278,611. (No model.)

mal position, actuated by the described arm and weight, and the points 9 catch against the inner end of the cylinder, the inner orifice, 9 of. which stands transversely to the opening I; when thelatter registers with the outer opening thereof.

H H are bearings secured within the front and rear ends ofthe Opening 0, and I is an upstanding weighted bar having trunnions i on its lower end journaled in said bearings. k is a shoulder on the lower end of said arm, which shoulder bears on the arm K, rising from the coupling-cylinder.

L is a shaft journaled on a proper part of the end of the car, having the crank Z on its outer end, to the outer side of the car, and the arm Z on its inner end.

M is a cord or chain connecting the end of the arm Z and a proper part of the bar I, so that when the said shaft L is turned by means of the crank Z the bar I bears on the arm and turns the coupling-cylinder in such position that the inner orifice of the same assumes a vertical position and registers with the entrance-opening of the draw-head, permitting the link-bar to escape.

Having described my invention, I claiml. The combination of the draw-head having an elliptic entrance-opening, the lockingcylinder arranged in the draw-head and having a twisted bore and provided with an up wardly-projecting arm, K, the bar I, pivotally mounted on the upper side of the draw-head and bearing on the arm K, and-mechanism for operating said bar I, as set forth.

2. In a car-coupler, the combination of the draw-head having an elliptic vertically-extended entrance Opening and provided with the Openings O and D, the lockingcylinder having a twisted bore and provided with an arm, K, projecting through the upper opening, 0, of the draw-head, the pivoted weighted bar I, having a shoulder, 70, to bear on said arm K, the crankshaft journaled on the end of the car and provided with an Outstanding arm, Z, and the cord M, connecting the arm Z and the weighted bar, substantially as specified.

3. In a car-coupler, the combination of the draw-head having an elliptic vertically-exwith the entrance-opening of the draw-head, 1o tended entrance opening and provided with substantially as described.
